PIN ID Scrappers and fakes
If you purchase bulk pins at cheap prices your most likely going to get a majority of fake or scrapped pins. They're cheaply made and can sometimes be identified by incomplete waffle stamp or stub points on the back of the pins. There used to be a great guide online.
so if you happen to get one or buy one long as your don't trade it or sell it to someone else and keep it for your own personal collection are they not a big problem if you keep for yourself?if someone could go in depth a little I'd appreciate it.
